我们报道了一个包含25毫米MgO:PPLN晶体的光学参量振荡器产生了带宽为200纳米、波长为3.5µm的中红外脉冲,并由光纤放大的Yb:KYW激光器发出的啁啾脉冲同步泵浦。长非线性晶体允许将泵浦带宽有效地转移到空闲脉冲中,实现了卓越的无源稳定性,并且可以直接使用光纤放大器的啁啾脉冲进行泵浦,避免了使用有损脉冲压缩光学器件的需要。
We report the generation of 200-nm-bandwidth mid-infrared pulses at 3.5-µm from an optical parametric oscillator incorporating a 25-mm MgO:PPLN crystal and synchronously-pumped by chirped pulses from a fiber-amplified Yb:KYW laser. A long nonlinear crystal permits efficient transfer of the pump bandwidth into the idler pulses, achieves exceptional passive stability and enables pumping using chirped pulses directly from a fiber-amplifier, avoiding the need to use lossy pulse-compression optics.
